E&OE Overview The 5A MPPT Solar Panel Charging Module with Display has a variety of applications including a DIY voltage regulator, charging module for a variety of batteries, step down convertor and power supply for electronic devices.Note: Detection module, please do not directly connect the output of negative electrode and the input of negative electrode. use a diode between the battery and the board Features Lithium-ion (Li-ion) / Lithium Polymer (Li-Po) Typical Voltage: 3.7V nominal (4.2V fully charged) Configuration Example: 1S (4.2V), 2S (8.4V), 3S (12.6V), etc. Charging Method: CC-CV is ideal ✅ Yes, fully compatible (with voltage carefully set per cell count) LiFePO₄ (Lithium Iron Phosphate) Typical Voltage: 3.2V nominal (3.65V full) Configuration Example: 1S (3.65V), 4S (14.6V), etc. Charging Method: CC-CV, but lower voltage than Li-ion ✅ Yes, just set voltage to 3.65V per cell 3. Lead-Acid (SLA, AGM, Gel) Typical Voltage: 6V, 12V, 24V Charging Method: CC-CV is suitable ✅ Yes, set voltage accordingly (e.g., 13.8–14.4V for 12V battery) NiMH / NiCd ❌ Not recommended: These require pulse or delta-V detection, not CC/CV. You could trickle-charge them, but it's inefficient and risks damaging the cells. ⚠️ Important Usage Notes Always use a battery management system (BMS), especially with Li-ion or LiFePO₄ packs. Set the voltage limit exactly to prevent overcharging (e.g., 12.6V for 3S Li-ion). Set a safe current level — typically 0.5C to 1C of battery capacity. For example: A 2000mAh (2Ah) battery: max safe charging current = 1A–2A Specifications Module Properties: Non-isolated buck module Input voltage: 6-36V DC Output voltage: 1.25-32V DC continuously adjustable (the default output 5V) MPPT voltage setting range: 6-36V Output current range: 0.05-5A (The default output current is 3A) Turn lights output range: 0.01-5A (default turn lamp current 0.3A) the current range will be a little difference because the parts parameter error. Multifunction double display: input voltage, output voltage, output current Operating temperature: -40 to + 85 degree Operating frequency: 180KHz Conversion efficiency: up to 95% (efficiency, input & output voltage, current and pressure-related) Short circuit protection: Yes Over temperature protection: (automatically shut off the output after over temperature) Input reverse polarity protection: None, (if necessary, please add the string into the diode) Output anti-anti-irrigation protection: no, the output must be connected to the battery plus blocking diode, otherwise it will burn the module! Charging indicator: charging red, bright green when fully charged. Turn lamp is the output current detection. Size: 60 x 31 x 22 mm Applications: DIY a voltage Regulator, with constant current function, Short-circuit proof, can protect the load. Power supply for electronic devices. For a variety of battery chargers, can observe the state of charge. Charger for various types of batteries, with MPPT function, can enhance the charging current to double. With a constant current and prevents battery overcharge, effective protection of the battery. Can support high-power LED. Package includes: 1 x 5A MPPT Solar Controller Videos
